To all whom it may concern: e

Be it known that I, GEORGE KU'rz, a citi- .zen of the 'United States, residing at Easton, 1n the county of Northampton'and State of Pennsylvania, have invented new and useful Improvements in Incubators, of which the following is a specification.

This invention relates to incubators and embodies in its organization a box creasing provided with an incubating chamber and an underlying broodingchamber, together with a heating apparatus through the medium of which the air within the casing is properly heated for hatching the eggs.

The invention has for its objects to provide a comparatively simple, inexpensive device. of this clulracter wherein-tlieheated air will be properly,circulated over the incubatirig chamber, one in whichthe amount of'lieat admitted to the 'casing will be auto- .rnatically controlled and regulated, and one wherein fresh air will be continuously ad- 4 rnitted to and properly circulated inthe incubating chamber for Ventilating tlie saine, the ventllatxng air `being properly warn'ied during itsadmission to the chamberv Pfor ob- .viatingimproper chilling of the eggsl v A further 'object of the invention is to pro` 4vide a device of Ithis character wherein the egg receiving tray may be readily adustcd forturning the eggs and to accord Vwith the i degree of heat ywithin the chamber, one in lwhich the-chickens may, when hatched, pass readil from the incubator to the brooding cham er, one wherein fresh air will be properly admitted to and for Ventilating the last named chamber, and one vin which the quantity of air admitted to the broeder may .bbdyingfthe invention. Fig. 2 is a' vertical4 transverse section taken on the line 2--2 of Fig. 1. Fig. 3 is a horizontal section taken-- mule une 3-3 of Fig. 1. Fig. 4 is s detail, @so

sectional view taken on the line 4-4 of Fig; 1 showing the manner of supporting the. egg tray. Fig. 5 is a planvview ofthe egg trav. Eig. 6 is a detail .sectional View taken,

longitudinally through the cooperating ven- 6,5 .,I

tilating slides, showing the saine open. Fig. 1

7 is a similar view, showing the slides closed. Referring to the. drawings, 1 designates a box or casing sustained by suitable sup ort.`

ing legs 2.and having uponits interior a ori- 7 zontal partitiondfl forming a heating chamber 4 and an'incubating chamber 5, in whlch lat-l ter there-is sustained an egg receiving tray 6 spaced from the bottom of the casing to form connection that the-bottom of the casing is provided with an enlarged opening 8,- for, apurpose Awhich will hreinafter appear. l'

Formed atthe forward endfo the casing l a brooding chamber 7, it being noted in this 75 by means of a vertical partition 9Vis a flue` 1() 80 which 'opens at-its upper end into the heating compartment 4. Sa1d partition is hollowto provide a dead air space 9l and. hence' 1ncrease the eiciency of said partition as allione conductor of heat. Attached to the bottom 85 of thelcasing immediately beneath the flue is a metal lamp box or case 11 .containing a lamp 12 and having at its u per end a'. series of air inlet openings 13 an an exit y,port or mouth 14 disposed immediately above the 90:

L' 'pivot and terminates in a pair of reversely inclined discharge portions 21 which direct thel incoming air toward opposite ends of the chamber 5, it being observed'that the ipe 19 tube 15, whereb through the venti ating tube will be properly warmed before entering the chamber 5.

Fixed beneath the o en bottom of'the casing 1 is a pair of gui e rails 22 having in turned horizontal supporting .flanges 23 adapted to sustain'a pair of su erposed ventilating slides 24, 25, provide respectively with longitudinal openings or slots 26 and ofV which the slide 25 1s movable relative to the slide 24 for bringing the openin 26, 27, into and out of register, there being ormed on the slide 25 an end rail 28 constituting-'anabutf ment for limiting the relative movement of 2o the slides when the openin' therein a're non-register, while seated a ove'and spaced from t e burlap or other pervious fabric and serving 'llhe tray 6 is supported between-its ends on a vertical bearing rail 31 and atl-its forward end by means of a wedge-shapedsup'-` .porting block 32 arranged for movement on an inchned rail 33, it being noted that the rail t 31 is positioned in rear of the center of the tray whereby the forward end hereof is over- .balanced and' may, when the block 32 is moved downward on the rail 33, swing downward at its forward end for a purpose which will hereinafter appear, there eing disposed above the tra a guide wire 34 on which'is suspended an for movement longitudinally vof, the wire a thermometer 35 designed for determining the temperature of the air circuv lating over the eggs. The tray 6 which has a bottom 36 composed of wire gauze or other suitable reticulated material is provided at its yforward end with a section or ledge 87 onto which the chickens ass from the re ticulated fabric and whic in turn has an I escape opening 38 normally closed by a slide 39 and which when open allows the chickens to brooding chambei""'7. Pivoted adjacent its rear end in a bearing -'40 is a rod 41 extended horizontally above the top of the casing and having in rear of its an adjustable weight 42 adapted to 'counterbalance the forward end yofv the rod, -w ich carries a valve 43 disposed above and vfor closing the upper end of the heating tube y'15',"while connected,. with the rod 41 at a *i 'point immediately in advance of it's pivot is a v vertically depending rod 44 extended downward through the top of the casing into the "'chamberand provided at its lower end and within the latter with a rheostatv 45 ofusual i i forni adapted through expansion to raise the forward end of rod 41, thus to move the disk eating. the fresh air taken in` upon the heat-will pass upwar .uppermost slide 25 is a frame 29l covered with a pair. of spaced sheets 30 of` drop from the tray into 'the 43 away from the upper end of the pipe 15 and decrease the amount of heat 4entering the chamber4i,

In practice, the tray 6 havin the e gs ar# nranged therein is positioned in t e incu ating chamber and the lamp 12,' is lihtlprd, wllieiit oug t e" duct 15 and thence through the'branch ducts -16 into the heatin chamber 4 throughwhich the heated airwi be circulated by 4means of 75 the delector 17, as heretofore explained,

4thus to heat the incubating chamber, lto I which-fresh airwill be admitted for purposes of ventilation throu h the Ventilating pipe 19, thcair passing't ough said pipe'being 80 warmed prior to entrance into the chamber 5 owingl to .the proxiinit of said lpipe, to the heating pipe .15, as" eretofore explained. Should the. heat within-,thcchamber 5 reach :beyond a-4 predetermined degree the rheostat.. g5

45 will be expanded'iiunder the action of the heat, thus raising the rod-41 and liftingthe valve 43 from the upper endof the pipe 15- whereby the quantity of the 'heated air wi esca 4 e eely from the pipe. 15, thus decreas- 90 ing t e quantity of heat entering the chamber 4 and,y lowering the temperature ofthe incuhating chamber 5, it being evident that as the temperature fallstherheostat will, under contraction, allow the v`r6df41 to move ydowu- 95 ward,- thu s closing' or practically, closing the upper end ofthe pipe 15, whereupon the heat. will again enter thechamber 4. If the. teniperature at the forward end of the tray which ow to its location near the flue `10 is sub- 1o( jec to the' greatest 'amoimt of heat bef comes too great `the block 32 may be moved downward on the inclined track 33, thus allowing the adjacent end of' the tray to de scend for equalizing the heat. It may be i mentioned in this connection"A that the forwardendV of the tray'may also be lowered urthe operation of turning the eggs and after lthe eggs have hatched for causing the chickens t'o pass" downward onto theledge 37 110 thi'ou b. the opening 38into the-brooding cham er. vThe chamber 71 is-ventilated' by' air percolating through the burlap sheets 30, the uppermost of which forms a soft founda- Vtion on 'whichthe chickensrest' itbeing un- 115 derstood .that the quan'tity'j.l o passing l intcth chamber vthrough t e .burlap 'maybe regulated or wholly cut oi proper' relative ad ustment of the slides 24,125.1? 1 Y )lhe lamp casing '11 ispi'ovided with anair. 120

In the operation of the device if the lamp radiates an undue degree of hea-t the element 49 will fuse, thus allowing the valve 47 to c lse under the action of weight 54 for cutting Qff the supply of air to the lamp casing Aand at the saine time permitting the Weight 4S to descend upon the push button 50, thereby pressing the saine into contact with the member 51"':xnd conipletiiig the electric circuit l'or sounding the alarm, thus to advertise the fact that the lamp requires attention.
